Product Introduction & Supply Chain Strategy

The GE Fanuc IC693PWR331C is a 30 Watt high-capacity 24 V DC power supply module engineered for Series 90-30 PLCs. Designed for DC-powered control cabinets, marine/offshore installations, and mobile equipment, it converts 18–30 V DC input power into precise backplane logic power (+5 V DC at up to 30 A) and auxiliary loop/relay power (+24 V DC).

Securing the IC693PWR331C as New Surplus is a critical supply-chain safeguard for facilities operating Series 90-30 systems on 24 V DC plant power. Sourcing factory-fresh, uninstalled original inventory eliminates the high risks of electrolytic capacitor drying, voltage ripple instability, and thermal stress degradation common in second-hand power modules, guaranteeing clean logic power without expensive platform overhauls.

 

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

  1. Execute Lock-Out/Tag-Out (LOTO) procedures on the 24 V DC main supply source feeding the PLC enclosure.
  2. Verify that line supply voltage falls within 18–30 V DC before wiring the input terminal strip.
  3. Inspect and install a fresh 3 V DC RAM backup battery (IC693ACC301) in the front battery compartment if replacing a main CPU rack power supply.

Stage 2: Removal

  1. De-energize primary 24 V DC input power to the rack. Unclip the protective terminal cover and disconnect incoming wires (+24V, Return, Chassis Ground).
  2. Squeeze the module release levers at the top and bottom of the IC693PWR331C housing.
  3. Slide the power supply straight forward out of the leftmost baseplate slot.

Stage 3: Installation (Seat & Wire)

  1. Align the rear card edge of the replacement IC693PWR331C with the leftmost slot guide rails of the Series 90-30 baseplate.
  2. Press firmly on the top and bottom face of the module until both retaining latches click locked.
  3. Reattach incoming power leads (+24V, Return, Ground) to the front screw terminals and secure the protective clear cover flap.

Stage 4: Power-On & Testing

  1. Reapply 24 V DC power to the terminal block.
  2. Observe front panel LED indicators: verify that the “PWR” (Power) LED lights solid green, and “OK” / “RUN” status indicators show normal startup.
  3. Check 5 V DC and 24 V DC voltage levels across baseplate test points to confirm stable power regulation under full module load.

Firmware/Software Versions & Upgrade Notes

  • Software Configuration: The IC693PWR331C is a passive hardware power supply and requires no software or firmware configuration in Proficy Machine Edition or Logicmaster 90.
  • Revision C Enhancements: Revision C includes upgraded surge filtering and improved heat dissipation over earlier revisions (e.g., PWR331A / PWR331B), offering higher noise immunity in harsh industrial electrical environments.
  • Slot Compatibility: Mounts exclusively in the dedicated leftmost slot (marked “PWR”) on all IC693 Main, Expansion, and Remote Baseplates.

 

Frequently Asked Questions (FAQ)

Is this power supply brand new or pulled from a used rack?

This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned panel, and not refurbished. All power supplies undergo full quality verification to ensure OEM-level reliability.

What is the main operational difference between the IC693PWR321 and the ?

The IC693PWR321 requires 120/240 V AC or 125 V DC input power and delivers up to 15 A at +5 V DC backplane power. The accepts 24 V DC input power and provides a high-capacity +5 V DC output up to 30 A for heavy backplane load requirements.

Why is buying New Surplus especially important for PLC power supplies like the ?

Power supplies contain electrolytic capacitors that degrade over time, especially when exposed to continuous heat in used industrial panels. Dried-out capacitors cause high output ripple voltage, causing random CPU faults and intermittent I/O card resets. Buying New Surplus guarantees fresh internal capacitors and 100% operational life.

Can the be used in expansion racks?

Yes. It can be installed in the leftmost slot of any Series 90-30 baseplate (CPU Main Baseplate, Expansion Baseplate, or Remote I/O Baseplate) operating on a 24 V DC supply system.

Does the supply battery power to retain CPU memory during outages?

Yes. The houses the 3 V DC lithium battery connector that maintains volatile RAM memory in Series 90-30 CPUs when primary power is removed.

What warranty coverage is included with this New Surplus power supply?

This power supply module includes a full 1-year functional warranty. If any operational defect or hardware failure occurs during normal use within 12 months, we will immediately supply a replacement unit from our active buffer inventory.
